Molecular dynamics study of structure formation at spreading of nanodroplets composed of rod-like molecules

Spreading of nanosized droplets has been simulated on the basis of isothermal molecular dynamics. Observed effects include orientational ordering and cluster parquet structure formation in nanodroplets composed of rod-like molecules. These peculiarities are observed for both continuous (structureless) substrates and structured (heterogeneous) surfaces represented by high- and low-energy segments, such as striped substrates and surfaces with quadratic high- and low-energy inclusions.
